Differential Diagnosis between Low-Grade and High-Grade Astrocytoma Using System A Amino Acid Transport PET Imaging with C-11-MeAIB: A Comparison Study with C-11-Methionine PET Imaging

<div>A case of a seventy-one-year-male who had newly diagnosed GBM in the left corpus callosum by stereotactic biopsy (malignant group) (case #13). A clear margined tumor was depicted as a high uptake of MeAIB lesion. MET-PET also demonstrated the lesion with the physiological uptake. Higher <i>T</i>/<i>N</i> ratio was noted in MeAIB-PET image.</div>
